Third party modules can be incorporated into BetterForms apps. This opens up en enormous library of open source and paid modules. You should have a good working knowledge of VueJS and how binding works.
The easiest modules to incorporate into BetterForms are Vue based. Most Vue Modules start with v-someName
Currently modules will need a CDN link and must install themselves. (See limitations below)
We will add v-calendar a beautiful date picker.
To reference the source code we will add the CDN link by adding the following to the DOM Header insertions for you site. The first line adds the CSS style sheet, the second is for the module code.
This module installs itself and will be available in HTML elements.
In the documentation for this library (https://vcalendar.io/) we see:
Here the :attributes key is bound to a variable called attrs To make the BetterForms compatible, we need to bind the atributes key to a BetterForms data source. We will use model like this: (remember: an attribute must have a colon in front of it to be compatible with Vue bindings)
The v-model in the component points to the data source used to populate the calendar.
This code is inserted into an HTML element and we are done!
There are some limitations when adding 3rd party libraries.
Module libraries must be available via a CDN
Modules must self install as a global Vue component
Modules must not require initialization code and be ready for use as a Vue component
Modules that are not Vue components can still be used but will often require writing small JS interface code to help patch them into the BF framework.
Be sure to make not if the type of links as some are cached much slower than others, see: https://forum.fmbetterforms.com/t/cdn-advice-if-your-site-is-slow-to-load/239
